Helsinki Airport opened in 1952 at Vantaa, just in time for that year's Summer Olympic Games. It replaced the older airfield at Malmi, which was too small for bigger planes. The first terminal was a modest building. The airport grew steadily as Finnair expanded from a small domestic airline into an international carrier, one of the oldest airlines in the world still flying today.
Helsinki's location gave it an edge. It sits on the shortest routes between much of Europe and northeast Asia. In 1983, Finnair began flying to Tokyo over the North Pole, then the fastest link between Western Europe and Japan. After the Cold War, the airline built a strategy around fast transfers. It kept the airport compact so passengers could switch between Asian and European flights in under an hour.
Terminal 2 opened in 1999. A major building project finished in the early 2020s. It added a striking new departures hall with a wooden roof and a much bigger area for flights outside Europe's open border zone. A rail line linked the airport quickly and directly to the city in 2015. Helsinki is still Finland's main gateway and one of Europe's most consistently efficient airports for changing planes.
